My p <br /> on the interpretation that the framed wall on top of the <br /> concrete would result in a horizontal resistance component <br /> owing to the anchor bolts . However , I agree that this is not <br /> comparable to framing a floor at the top of the wall with <br /> full lateral thrust resistance as for a basement wall . <br /> On the other hand, a 6-ft ht wall without any surcharge <br /> loading contributing to the active earth pressure component, <br /> would require less reinforcement than that provided on the <br /> plans . <br /> I am attaching pp 384-385 of the same ancient CRSI design <br /> handbook with the reinforcement requirements for a 6-ft wall . <br /> act�inlaemannerrequivalent tofthe specifiedrbasefwidthgand to <br /> depth. <br /> I also understood your query to include an examination of the <br /> long axis seismic force component action on the garage door <br /> structural line. At the first floor level , there are 4 <br /> north-south structaral frame lines . Ttie framing around the <br /> garage door openings must be configured to transfer the <br /> lateral push component of the sesimic load. <br /> The prior calculations include the estimate of the seismic <br /> loads . The followinq pages include: <br /> 1 . Distribution of story shear to determine the lateral <br /> seismic push at the story level - frame line in <br /> question. <br />
